Application filed February 28, 1907. Serial No. 359,831.v

To all whom it may concern:

Be it known that I, PEROY GEORGE ARMI- TAGE, a citlzen of the United States, residing at 40 Congress street, in the city of Newark,

county of Essex7 and State of New Jersey, have mvented a certain new and useful Improvement in Portable Striking-Bag Plat-l forms, of which the following is a specifica-` tion, reference being had to the accompanying drawings, which form a part of the same.

The object of my invention is to provide a platform which can be readily mounted between a doorway or other similar space without boring holes, and also have the parts so i connected that they can very readily be in- L the brace support may be tightened by one turn-buckle. Fig. 6 shows the ring in colla sed position.

eferring more particularly to the drawings, 1 1 represent sectional brace supports, the inner end of one of which sections is provided with a right-hand screw thread while the inner end of the other section is provided with a left-hand screw thread. The outer ends of these sections fit into the recesses 2 2 in the brace blocks 3 3. Cushioned surfaces 4 4 are preferably provided for the opposite sides of these brace blocks so as to give them greater holding ability when pressed against the jalnbs 31 of a doorway or other suitable opening.

5 5 represent turn-buckles connecting the inner ends of the brace supports 1 1. These turn-buckles are provided with righthand and left-hand nut threads to correspond with the right-hand and left-hand screw threads of the brace supports. It will readily be seen that the mani ulation ol' these turn-buckles tightens and loosens the brace supports as may be desired. The brace supports are hinged at 6 6 the rod 7 performing the double function of hinge* pivot and connecting link for a pair of brace supports. These hinges permit the folding of the brace supports when not in use.

Clamps 8 8 t over the upper brace support 1 as shown and are adapted to be tightened upon said brace sup ort by means of the thumb-screws 9 9. etween the ends of vthese clamps are pivoted the oblique supporting rods 10 10 which at their opposite ends are connected with the horizontal supporting rods 11 11 as hereinafter described. y

12 12 represents suitable clamps on the lower brace support between the ends of which are held the horizontal supporting rods 11 11. The thumb-screws 13 13 are adapted to tighten the clamps l2 12 and fasten the horizontal supporting rods l 1 11. The oblique sup orting rods 10-10 are fastened into the c amps 8 8 by means oll the screws 9 9.

The ring is made up of sections 14. These sections are shown as being hinged together at 15' 16, the former being a single hinge while the latter is a double hinge. It will be seen that upon the section connected by the single' hinge being folded upon its adjacent section, the section connected by the double hinge may be completely Jfolded down on the section first referred to, making a compact compass. provided with a suitable locking mechanism. This locking mechanism consists of a male member 17 which contains a recess 18 adapted to receive the pin 19 pressed by the spring 20 which pin slides in the sleeve 22. This male member which is connected with one of the free ends of the ring is adapted to slide into the female member 21 connected with the other free end of the ring. The ring is fastened to the supporting rods 10 10 and 11 11 by means of the thumb screws 23 23, which also fasten together the connecting ends of the said supporting rods. The cross bar 24 fits across the ring 25 as shown the ends of said cross bar being secured to the ring by means of the screws 26-26.

33 is a steadying bar which is connected at its ends 32 32 with the horizontal bars 11 11, 32 showing the steadying bar following-the contour of the ring. The bag 27 is suspended from the cross bar 24 by means of the rope 28.

In Fig. 5 I have shown a modified form of brace support by means of which only one turn-buckle is used instead of two turnbuckles as shown in Fig. 1. In this modification 29 30 represents telescoping rods connecting with the brace block 3. The manip- The free ends of the ring are ulation of this brace device is controlled from the turn buckle 5 as is obvious from the drawings.

It is of course apparent that those familiar with this art may make many modifications in the size, proportion and number of parts of this device. .Parts of the same may be used without employing the whole and parts may be used in connection with other devices without departing from the spirit of this invention or lessening the advantages of the same. I do not therefore desire to be limited to the disclosure which has been made in this case, but

What I claim as new and what I desire to secure by Letters Patent is set forth in the appended claims.

l. In a striking bag platform a pair of sectional hinged brace su )o1-ts, turn buckles connecting said sections, race blocks, means for supporting the platform ring, removably connected with the brace supports, a platform ring, means removably connected with said ringI for supporting a suspended striking bag substantially as and for the purpose set forth.

2. In a striking bag platform, sectional brace supports, hinges connecting the adjacent ends of said brace supports, turnbuckles connecting the sections of said brace supports and adapted to extend and distend the same, a platform ring, and means removably connected with said supports for removably supporting said ring, substantiallv as and for the purpose set forth,

3. In a striking bag platform, a ring composed of sections, means for suitabl)Y eonnecting said sections to each other and intorlocking means for connecting the ends thereof substantially as described.

4. In a striking bag platform, a ring` eomposed of sections, a single hinge connecting two of said sections, a double hing(` conneriing two of said sections and interlocking mechanism connecting the remaining ends oll said ring substantially as set forth.

5. In a striking bag platform, horizontal supports, a steadying bar, means for ronnecting the same at its ends with said horizontal supports, a platform ring, and means f for securing the said ring to said har, suhstantially as described.

6. In a strikingbag platform, horizontal supports, a platform ring, a steadying bar supporting the ring, and means for connecting the steadying bar at its ends with the said horizoiital supports, such steadying bar having substantiallv the contour through its travel of the platform ring, suhstantiall \v as described,
